[ Upstream commit 1d3062fad9c7313fff9970a88e0538a24480ffb8 ]
smatch reports:
drivers/gpu/drm/drm_file.c:967 drm_show_memory_stats() error: uninitialized symbol 'supported_status'.
'supported_status' is only set in one code path. I'm not familiar with the code to say if that path will always be ran in real life, but whether that is the case or not, I think it is good to initialize 'supported_status' to 0 to silence the warning (and possibly fix a bug).
